A slice of a round pizza is shown below. What is the length of a?

4.71 in

Step-by-step explanation:

The shape above can be liken to an arc.

The following data were obtained from the question:

Angle sustained (θ) = 45°

Radius (r) = 6 in

Pi (π) = 3.14

Length of arc (L) = a

The length of the arc can be obtained as follow:

L = θ/360 × 2πr

a = 45/360 × 2 × 3.14 × 6

a = 0.125 × 2 × 3.14 × 6

a = 4.71 in

Thus, the value of 'a' is 4.71 in

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
